Abstract

Flame-resistant thermoplastic branched polycarbonates of high molecular weight are prepared from:
  • (1) a carbonate precursor;
  • (2) at least one dihydroxyaromatic compound of formula: where:
    R is a single bond, or a substituted or non-substituted linear or branched C₁-C₅ alkylene radical, or a group chosen from O, S, SO₂ and CO;
    X and Y, which may be the same or different, are H or CH₃;
    m and n, which may be the same or different, are whole numbers from 1 to 4;
  • (3) at least one halogenated carbonyl compound of formula: where: Z is a group chosen from O, S and NH;
    R₁ and R₂, which may be the same or different, are chlorine or bromine;
    R is hydrogen or chlorine or bromine or a C₁-C₃ alkyl radical;
    p is zero or 1 or 2.
